I agree, they are first of their kind so right now its more trial and error as far as how things will go with them. Once they have established themselves as far as looks, health, fertility, that sort of thing, thats what could drive price up or down. From a business stand point, when a product is new to the market, sales reps typically give samples or discounted rates to get the word/product out there to the customer. Once the product is proved to be liked and a demand is created, price is driven by the supply and the demand.
